Computer hacker Marcus spends most of his time outwitting school surveillance, until the day that San Francisco is bombed by terrorists -- and he and his friends are arrested and brutally interrogated for days.

For Marcus, the only option left is to take down the power-crazed Department of Homeland Security with an underground online revolution. -- Description by Ellen Foreman
